How do I edit a space that I created?

Edits to your space are made via the same Space Generator you used to initially create it. 

The easiest way to access the generator is by navigating to your space on the Spaces tab and tapping the name of the space at the top of the screen – which brings up the Space Details page.

Next, tap the pencil icon at the top of the page to access the editor. Once you have finished making your changes, make sure you tap Save at the end of the flow in order to publish your updates.
